Nightmode / Darkmode for pEp Android

Thank you for your work. I really like pEp.
But for eye comfort please add a nightmode/darkmode to the Android version (I'm using the F-Droid version) of your program.
It's very hard for me to read emails at evening or night with your Android application because it hurts my eyes and irritates the human cirdian rhythm (sleep wake rhythm) because the bright white light that comes from the standard day theme of your application activates to much of the eye receptors for daytime.

I'm sure a lot of other folks will also be thankful for a nightmode too.
Thank you

Ah that's good to hear! I really appreciate that. What do you think about the rough estimated time schedule for the first version of the nightmode? Or isn't it possible to target?

I'm not a software developer so I don't know how hard it would be to implement that or how much work that would be, but I can tell you what my dream version of a nightmode would look like:
A easy customizable theme engine would be a killer feature! Where you can easily set your favorite colors for the text and the background. For example a black background with red text, green links, purple visited links and so on. The Theme engines used in the Android Applications from Simple Mobile Tools (also installable from F-Droid) or the Dark Background and Light Text Firefox Add-On are really good examples for how it could/should be in a perfect version.

Ok sure. Thank you

Ok that's cool. Thank you! I'm curious to see it, when it's ready to install from F-Droid.

Version 1.1.251 finally arrived in F-Droid on 2021.04.29! Thank you so much!
